Yes I ended up using mpos as a base. I was having a hard time getting the one I was making from scratch to communicate with the database. If I can get it off the ground it might be worth my time to attempt a full custom front end again!
Definitely MPOS. I do like the look.
I was going to suggest re-adding the original creator's footer to the site somewhere but I found it under the "About" section.
Nice and clean, well done.
